In molecules there are certain groups of atoms that are able to rotate. This movement occurs under the influence of random stimuli from the environment and is not continuous but occurs in jumps. It is generally believed that such jumps occur in a manner that is typical of classical objects, such ...

At very high energies, the collision of massive atomic nuclei in an accelerator generates hundreds or even thousands of particles that undergo numerous interactions. At the Institute of Nuclear Physics of the Polish Academy of Sciences in Cracow, Poland it has been shown that the course of this ...

Light initiates many chemical reactions. Experiments at the Laser Centre of the Institute of Physical Chemistry of the Polish Academy of Sciences and the University of Warsaw's Faculty of Physics have for the first time demonstrated that increasing the intensity of illumination some reactions can ...

The world around us is mainly constructed of baryons, particles composed of three quarks. Why are there no antibaryons, since just after the Big Bang, matter and antimatter came into being in exactly the same amounts? A lot points to the fact that after many decades of research, physicists are ...

Holographic atomic memory, invented and constructed by physicists from the Faculty of Physics at the University of Warsaw, is the first device able to generate single photons on demand in groups of several dozen or more. The device, successfully demonstrated in practice, overcomes one of the ...

Our intuition tells us that a sample of material compressed uniformly from all sides should reduce its dimensions. Only a few materials subjected to hydrostatic compression exhibit the opposite behaviour, expanding slightly in one or two directions. At the Institute of Physical Chemistry of the ...

Alexander Filippou, Professor of Inorganic Chemistry at the University of Bonn, Germany, received the 2016 WACKER Silicone Award. The award was presented at the eighth European Silicon Days in Poznań, Poland. The Munich-based chemical group thereby recognizes Filippou’s groundbreaking work in the ...

Unique optical features of quantum dots make them an attractive tool for many applications, from cutting-edge displays to medical imaging. Physical, chemical or biological properties of quantum dots must, however, be adapted to the desired needs. Unfortunately, up to now quantum dots prepared by ...

The chaos typical of liquid molecules, and the ordering characteristics of crystals. There are states of matter connecting such contradictory features: liquid crystals. Thanks to an innovative application of antimatter, it has been demonstrated at the Institute of Nuclear Physics of the Polish ...

Objects of the quantum world are of a concealed and cold-blooded nature: they usually behave in a quantum manner only when they are significantly cooled and isolated from the environment. Experiments carried out by chemists and physicists from Warsaw have destroyed this simple picture. It turns ...
